pr3 obd0 to p28 obd1 ecu
hey guys
i'm running a b16a first gen with a obd0 pr3 ecu on my 89 civic dx and i want to switch the pr3 ecu to a obd1 p28.
do you guys know if somebody makes a wiring conversion for this and if i'm going to need something else to be able to do this conversion.
thanks for any help you guys can give me.

Well youd probably have to chip it... Since im sure the fuel maps on the DOHC VTECs are more 'potent' than the P28s...
But yes, you can get a conversion harness from rywire...
Plus youll also need other things to do an OBD1 conversion... An OBD1 dizzy and a 4 wire O2 sensor... And an optional toggle switch (for the new check engine light of the OBD1 ECUs, u have to complete a circuit between 2 of the wires on the ECU to pull the codes from it, most just use a switch)...
